Application of Coupling Agents in Engineering Plastic Mixtures

Coupling agents, also known as surface modifiers, can reduce the viscosity of synthetic resins, improve the dispersion of fillers, and enhance processing performance in plastic processing. This is beneficial for the product to achieve good quality and performance. So what role do coupling agents play in engineering plastic mixtures?

Engineering plastics include many thermoplastic materials, all thermosetting twisted materials, and all reinforced and filled plastics. Typical engineering plastic blends include the following operational units:

1. Plastering

2. Distribution and dispersion mixing of additives (coupling agents, colorants, pigments, flame retardants);

3. The discharge of a small amount of volatile compounds;

4. Fill in as required;

5. Enhance as required;

6. Mix and alloy with other polymers as required;

7. Reactive extrusion;

8. Filtering (excluding impurities);

9. Create a location.

Compared to general bulk polymers. Engineering plastics are produced in small batches. Because there are various specialized requirements for finished products made of engineering plastics, requiring a large number of different formulas and special mixing conditions. The yield of early mixed materials in engineering is generally between 100-3000kg/h. In some special cases, the yield can reach up to 5t/h
